I have a carby 2011 mehran. Just changed engine oil 100 KM before and went to sahiwal from lahore. got my tank full from thokar byepass, used AC through out and drove very agressively. top speed with AC was 110. came back and refilled the tank. it costed RS 1330 and distance travelled was 374Km. out of which 30-40 km was inside sahiwal and its not a big city so top speed was 40-50
The average was above 18km/L with AC and I think its really impressive given its not EFI. have 94k on odo meter.
